Frequently Asked Questions

The difference between EVA and PUR glue, EVA ethylene vinyl acetate adhesives, while PUR makes use of polyurethane reactive adhesive. In the process of perfect binding PUR is prepared in much the same way as a traditional EVA-bound book, utilizing a variety of notching, roughing/milling heads in order to create fibre. The adhesive then will bond with these fibres during the curing process. the advantages of PUR are that it offers increased binding strength. As with conventional hot melt glues, the initial bond in PUR is formed as it cools and solidifies. Unlike conventional hot melts, PUR contains reactive components (isocyanate groups), which cure in the presence of humidity and form a strong elastomeric film. Furthermore, while EVAs properties allow it to be reactivated with heat, the film produced by PUR cannot be re-melted and is insoluble to most solvents. Thus, EVA binding exposed to extreme heat is able to melt, while a PUR binding will remain in its solid state. While PUR has some advantages it also can be costly in terms of maintenance and cleaning. The one-pot system requires a longer clean-up process than traditional EVA systems. The pot must be drained and the adhesive allowed to cure overnight before the pot can be reheated and any remaining adhesive removed. The adhesive pot may require recoating as often as once every three years. The system also allows for greater amounts of glue spoilage.

Please refer to the wire size chart on the wiring binding page.

Please refer to the size indicator on the comb binding page.

With EVA you have a much shorter time from binding to use. This is determined by the glue manufacturer. With PUR we highly recommend that the books are left for a 24-hour period before use to allow the glue to properly set.

It is very important to make sure that you use the correct size cover when thermal binding. If the cover is too small then there will not be enough glue in the cover to hold all the pages. It is also very important to cool the book long enough after the heating process to ensure that the glue is set. We recommend at least 1 hour before you start to open the book in the flat position.

This most commonly refers to the punching of the paper. The electric machines greatly increase speed and productivity. They also provide a much safer workplace for the staff.

There are many options from doing by hand to using cost effective electric winders.

The most common and cost-effective thermal binding covers are clear front white back. The white back is called chromolux. This is a very high gloss smooth surface.

The most popular type of back cover used is the leather grain cover. This cardboard has a texture that looks and feel like leather. PHE provide a full range of colours and thicknesses.

PHE sell a large range of all size calendar hooks.

You will need to purchase a machine called a calendar cutter. This will allow you to cut your product and also do round corner cutting.

This option is available on all QUPA binders. You will need to dis-engage your last punch and centre up your page. You can purchase 20 loop combs or just use scissors to cut your 21 loop combs.

Before you bind your book make sure you place your back cover on the front of your book. Once you have closed your wire you can flip your back cover over hiding the closed part of the wire between the back cover and the back page.

These are both commonly used words for the same process.

There is a large range of plastic combs that bind from 1 page all the way to 500 pages. 6mm to 51mm oval.

Yes, there are wires ranging from 6mm to 38mm. Please refer to the consumables page for each wire’s page capacity.

No. The wire is clamped closed therefore it is not able to be re-opened and used again.

Yes you can, plastic combs can be opened and closed enabling editing.

Perfect binding is an automated process of creating cover, pre gluing the insert pages and clamping together to create a finished booklet, normally used as a more commercial environment.

Thermal binding is the process of placing loose leaf pages into a pre- prepared pre glued cover, the machine melts the glue within the binder to adhere the pages.

Spiral binding is continuous hard plastic binding in a spiral fashion. This process uses an electric winder to insert spiral coil onto sheets.

Twin loop wire is 2:1 or 3:1 loop wire binding.
